"incorrect tag name" error

[marcellevi]

I've been using MinimServer & MinimWatch since Oct 4, included in a sonicTransporter setup (Linux media server). I'm not an advanced user, just want to have simple DLNA running on my network.

I just noticed that CD's I've ripped since Oct 4 weren't showing up, so I selected Rescan from MinimWatch. It immediately turned the icon red and the server stopped, with the following error message:

MinimServer: incorrect tag name 'Composer' in property 'tagCustom'
MinimServer error: now stopped, use 'restart' or 'exit'

Any advice on how to fix this? Again, I'm not an advanced user, but I found this in the Advanced Properties settings: (I assume it was the default as I surely didn't type it here.)

tagCustom: AlbumArtist.displayRole={artist}, Composer.displayRole={artist}
